### 3.1 Present Allocation Figures

An informal analysis of "network-contacts.txt" (available from the DDN NIC) indicates that as of 2/25/92, 46 of 126 class A network numbers have been allocated (leaving 81) and 5467 of 16382 class B numbers have been allocated, leaving 10915. Assuming that recent trends continue, the number of allocated class B's will continue to double approximately once a year. At this rate of growth, all class B's will be exhausted within about 15 months. As of 1/13/93, 52 class A network numbers have been allocated and 7133 class B's have been allocated. We suggest that the change in the class B allocation rate is due to the initial deployment of this address allocation plan.
